I'm donating the proceeds from this video to the Hawai‘i Community Foundation's "Maui Strong: Fire Relief Fund" to help support the people of Maui who lost so much in the wildfire. As a former resident of Hawai‘i, I was heartbroken to see the beautiful town of Lahaina destroyed.  If you are able to, please consider contributing, you can make a donation on the YouTube video. Mahalo!

Another new Arduino board! This time it’s the Arduino Nano ESP32, and we’ll test it out today. Includes MicroPython and Arduino IoT Cloud experiments.

Arduino has certainly been busy lately. After releasing the Arduino Giga at the beginning of the year, they followed up by releasing two new Arduino Uno boards. And, as if that wasn’t enough, they have just added another member to the growing Arduino Nano family - the Arduino Nano ESP32.

Although a few of the Nano boards already have ESP32 chips, those boards use the ESP32 as a communications coprocessor. This new Nano is the first Arduino board to use the ESP32 as its main processor.

We will begin by looking at the board features and pinouts. Of course, all Nano boards use the same pinout, allowing you to repurpose any prototyping tools you have gathered for the other family members.

At the heart of the board is an ESP32-S3 module, so the new Nano board has essentially the same specifications as other boards built around that chip.

We’ll also use the board with MicroPython, and I’ll show you how to install the MicroPython bootloader. Don’t worry; you can revert to C++ by reinstalling the Arduino Bootloader. I’ll show you how to do that as well.

And we will build a project for the Arduino IoT Cloud. The Arduino Nano ESP32 is an inexpensive way of creating IoT applications.

Here is the Table of Contents for today's video:

If Arduino releases any more new boards this year, I’ll need a new Arduino shirt! Hope you enjoy the video.

Just a couple of off topic things, when did printf support become available? A few months ago I was looking into that and found there is a 3rd party library for it. The discussions I found did not seem to know there was built in support. Much better way to do Serial.print for debug or just old fashioned printouts.

I see they have added a few goodies to the IOT cloud, maybe time to up my subscription.

Can you cover the difference between the IOT cloud and the Arduino cloud?

Lot's of new stuff, just in time for my new 'lab'.

Thanks as always, and donation done.

Arduino says and I agree, in general, the const keyword is preferred for defining constants and should be used instead of #define
